With sparring mode, Fritz will not always give you a tactical shot, even on the lower levels. Almost always, but not always. I'm not sure how it works, but I suspect it has something to do with the sort of positions you play into and whether Fritz thinks it has an opportunity to play a "realistic" blunder. I also suspect that, at the higher levels, you have to work harder and play better to set those opportunities up.
That's just my impression though, based on a few years of using it. If anyone out there knows anything about the implementation of sparring mode it would be interesting to hear it.
I have a question for any fellow Fritz users out there.
I've been using sparring mode pretty heavily in Fritz, the game type where the computer gives you tactical opportunities in the games against it. I've been winning consistently at the second highest setting so today I finally set it to the highest setting and was destroyed, but that's besides the point. The point is, after the game the computer always marks the moves where it has provided the player with a tactical opportunity, whether or not he takes advantage of it, but this particular game had nothing, zilch, zippo!
Now what I'm wondering is if at the highest setting, the computer only gives you a tactical opportunity once every two or three games, or whether maybe I made some kind of mistake in setting up the game in the first place. Has anyone else had an experience like this in sparring mode on very hard? Incidentally the game lasted 30 something moves, so, it wasn't like I blundered horribly in the opening and just didn't give the computer enough moves to give me something.
